PRESS'FOR EXTRACTINGOIL, 80C.

SPECIFICATION forming part of Letters Patent No. 632,158, dated August 29, 1899.

7 Application filed May 26,1899.

To all whom it may concern.-

Be it known that I, CHARLES E. SNYPP, a citizen of the United Siates,residing at Gretna, in the parish of Jefierson and State of Louisiana, have invented certain new and useful Improvements in Presses for Extracting Oil or other Liquids; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in horizontal presses particularly for use in expressing oil from cotton-seed meal and forming the meal from which the oil has been expressed into cakes, which have a commercial value, as well as the oil.

My invention will be understood by reference to the accompanying drawings, wherein the same parts are indicated by the same letters throughout the several views.

Figure 1 represents a side elevation of my press, partly in section. top plan view of the same, the feeding mechanism being omitted. Fig. 3 is a section taken on the line 3 3 in Fig. 2 and looking in the direction of the arrows. Fig. dis a vertical section taken on the line 4 4 in Fig. 2 and looking in the direction of the arrows, the view also being partially broken away, showing the interior of the press-plate. Fig. 5 is a section taken on the line 5 5 in Fig. 4 and looking in the direction of the arrows; and

Fig. 6 is an elevation of the press-plate, showing the face thereof as broken away to reveal the contracted openings in the backing.

The press comprises a horizontal set of adjacent press-boxes A, located between a series of plates, the latter being carried in frames A, having supports a, which are mounted upon and also slide along the horizontal stays A The pair of horizontal stays A and the similar pair of upper stays A are secured at their ends in cross-heads A and A constituting the rigid frame of the press. The frames car- Fig. 2 represents a i Serial No. 718,418. (No model.)

to each other, according to their location. The first press-frame, as seen most clearly in Fig. 3, has connected thereto a piston B, which works in a cylinder 13, connected to the cross-head A This cylinder is provided with a steam-inlet pipe I) for the admission of steam or other fluid under pressure for forc ing the press frames together. To the first press-frame, as seen in Figs. 1 and 2, is connected a pair of rods 0, which rods are connected at their rear ends to a cross-head O, and to the said cross-head O is connected a piston 0 which works in a pressure-cylinder C The piston C and its connections with I the first press-frame serve to draw the series of frames apart after the operation of pressing has been completed and when it is dej sired to remove the cakes formed in the pressboXes. The cylinder 0 is provided with .steam or other fluid inlet pipe 0 for giving the necessary pressure, which pressure, it is obvious, need not be nearly so great as that required in the pressing operation. The rearward movement of the piston O is l limited by means of the plurality of bolts 0 i which engage in flanges O and C on the said piston and on the cylinder, respectively, the i movement allowed, however, being suffi- 1 ciently great to draw the press-frames away from each other to the full limit permitted by 1 their connecting-bolts a as hereinbefore de- 1 scribed.

The press-plates are of the form and construction shown and described in my pending application serially numbered 707,793 and filed March i, 1899, and consist of a backing D, provided with grooves or slots cl, located in the central portion of the backing, as seen most clearly in Fig. 5, and with holes 5 d running from the front and rear surfaces 3 of the backing to the central grooves or slot-s id. Fitting over the front and rear faces of l the backing are plates E and E, which are. in contact with the said backing and are pro- I vided with holes 6 and a, shaped in the form of truncated cones, with their apexes next the backing. These holes or perforationse and e, however, are not arranged over the perforations d in the backing, which is an important point in the construction of my press- 1 plate. The plates E and E" are preferably frames may move more or less with respect fastened to the backing to retain them in position; but this is not necessary, and they may be held in place in any preferred way.

At the bottom of each of the backings D is formed a transverse channel d with which the slots or grooves d communicate and into which the oil passes from the said slots or grooves d. The channels d are provided with an outlet connection d with which may be engaged a flexible pipe for drawing off the oil to a tank or other point of collection. (Not shown.)

Upon one side of each of the pressframes are formed vertical flanges E between which the plunger side of the adjacent plate closely fits, the width of the flanges being so great that the plunger-face of the. telescoping adj acent plate is never quite wholly drawn there from, so that the sides of the press-boxes are at all times closed and the material being pressed is effectually retained in the pressboxes. At the upper and lower ends, respectively, of the press-plates and upon both faces of the frames are provided moldings or inclined ribs, as seen at e which when the faces of the adjacent plates are brought together upon the mass of material within the box impinge upon the upper and lower edges of the mass and prevent the extrusion of the material at these points, creating crimped edges upon the pressed cake.

F represents a door pivoted upon one of the horizontal rods A so as to form a bottom for the press-box when in its horizontal position, as shown in Fig. 4. This door is made perfectly continuous throughout the system of boxes and is provided with a plurality of counterweights F, which serve to render more easy the closing of the door. The swinging side of the door is provided with handles F and spring-catches F are arranged to engage the said handles F or studs f thereon, as seen in Fig' 4, for the purpose of retaining the door in its closed position. The said door is provided with depressions or channels f beneath the edges of the press-boxes for the reception of the oil and through which the oil may be conducted to any suitable outlet. The said door serves to retain the cotton-seed meal or other material to be pressed within the press-boxes prior to the pressing operation but after the pressing has been effected the catches may be detached from the door and the latter swung downward, so that when the press-frames are drawn apart the cakes may fall out.

H represents a cylinder within which runs a spiral conveyer H for feeding the meal or other material to be pressed to the pressboxes. The bottom of this cylinder is provided with an opening the length of the series of press-boxes, and in this opening is mounted a sliding bottom or plate H having a small opening 72 at one end thereof of the width approximately of press-boxes when the latter are open. At the extreme end of this sliding plate is rigidly mounted a downwardly-extending and inclined plate or chute h for the purpose of directing the material as it falls through the opening h in the sliding plate H under the action of the spiral conveyer H to any one of the press-boxes.

The operation of this feeding device is as follows: The meal enters one end of the cylinder H from any suitable source of supply, (not shown,) and the conveyer beingrotated by any suitable means (not shown) the plate H is moved to bring the opening 712 therein over one end box of the series of press-boxes and held in this position until this box is filled, when it is drawn along to the next box, and so on through the series, the boxes being thus filled in succession, after which the conveyer may be stopped. The press-boxes being all filled, pressure is admitted to the cylinder B, which, acting on the piston B, forces the press frames together, as hereinbefore described, and the pressing operation, during which the oil is expressed from the meal in the pressboxes, takes place. The pressure in the cylinder B is now released and pressure is turned into the cylinder G which pressure acting upon the piston 0 carrying the cross-head O and rods 0, connected to the first pressframe, draws the said frames apart, leaving the cakes free from the press-plates in the press-boxes. If the door F be now released and dropped, the cakes will fall out through the bottoms of the press-boxes into a suitable receptacle. Upon the door being returned to its closed position again the operation of filling and pressing may be repeated.

In operation it may be found that the pressplates E impinge so closely upon the backing as to retard to an undesirable degree the passage of the oil or other liquid or that the oil may partially solidify, and thus seriously retard the operation of the press, and in such case I propose to use a sheet of haircloth or other similar fabric interposed between the plate E and the backing, which will prevent the plate E lying too closely to the backing, while at the same time permitting of a perfect straining efiect.

Before starting the press it maybe desired to clean or heat the press-plates and the channels therethrough, and this may be done by connecting the pipes attached to the discharge-openings d with a steam-supply, and thus steam may beadmitted to the channels (1 and d in the backing D and caused to escape under restriction through the face-plates E and E, by which operation a thorough eleaning and heating may be efiected.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
